This invention refersto capping machines with several so called capping heads where the cap stamped out from a metal strip 'is inserted pneumatically and where it is then fastened automatically on the bottle. The invention has for its object to facilitate in machines of this kind the adjusting for bottles of different height. 7

In holder machines, that is to say, machines without neumatic insertion of the caps in the capping heads, these are mounted in a part of the frame which may be raised and lowered for adjusting the heads to the height of the bottles on the machine table which is stationary.

The said adjusting device cannot be used in machines with pneumatic insertion, because the opening of each capping head through which the cap is inserted therein ao must be of an invariable width determined exactly in relation to the horizontal surface on which the cap slides on to the opening. The fact thatthe machine may be adjusted to bottles of diflerent height or, in other 2 words, to the distance between the machine table and the ca ping heads is, evidently, very vital, as the mac ine otherwise cannot be use for more than one size of bottles. To make the machine table so as to be raised and lowered, which is close at hand, has met with difliculties by reason of the table being connected to a great portion of the mechanism- 7 of the machine. These diificulties are overcomeLby this invention which is described below and shown diagrammatically in the accompanying drawings, where- Figure 1 is a side-view, r l Fi re 2 is a horizontal section on the line II Iof Figure 1', and v Figure 3 is a side-view on a greater scale, partly a verticalsection.

The capping heads 1 for rotating on a column 2 which is fixed to the floor by a base-plate 3 and screws with 4 nuts 4, 5. Each head 1 has an opening 6 (Figure 1) for the insertion of the cap in the head, which is'efii'ected. when the head is on the back-side, considered from the spectator, and the respective cap is blown into the bpening on a path 7 (Figure 2). synchronously are as usual adapted with the heads 1 a nave 8 rotates in which supports 9 are disposed pushing up the bottles 10, each' into one head, when the cap is to be fastened on the bottle. The said nave 8 is surrounded by a casing 11 located round the column 2 so as to be raised and lowered, the machine table 40 resting on the said casing. The bottles are moved automatically out to the machine by an endless conveyor belt 12 running between guides 13 resting on up: rights 14. When the bottles, the one after the other, reach the machine they are seized by a turnable catcher 15 which places themeach on one support (Figures 1 and 3). An arched railway 16 guides the bottles in their movement with the catcher 15. During the rotation round the column 2 the bottles are maintained in their position each on its support by a ring 17 which synchronously partakes in the rotation of the heads and has a recess 18 for each bottle. Theheads 1, the nave 8 and the ring 17 are mounted on a tube 20 around the column, the said tube being supported by ball-bearings 21 resting on the base 22 of the column. The said tube is besides mounted around a bearing sleeve 42, and it is rotatated by a mitre wheel gearing 23, the shaft 24 being driven by mechanicalpower. The heads 1 are fixed to the tube 20, but the nave 8 and the ring 17 can be pushed up and down on the same. They are, however, caused to rotate with the tube by Wedges 25. The nave 8 is supported by an annular flange 26 in the casing 11, the said annular flange serving also as hearing for the nave. The upwards and downwards motion of the supports 9 is eflected by a cam 27 fixed to a shoul der il on the inside of thecasing. -When during the rotation of the nave 8 a support reaches the cam 27 a roller 29 on a pin 28 of the support rolls up on the cam,the support being then raised. When the roller has passed the highest portion of the cam the support sinks down again. At the same time as a cap is blown into a head lthe bottle is as moved under the said head'by the support 9 and the cam 27 respectively. When the sup-'- port has reached its highest position the neck of the bottle must be in a determined height position in the headl for allowing the cap to be fastened. The said position is determined by the raising or lowering of the supports, not se arately but commonly and together with t e whole casing 11 and members located therein, in order that the adjustment may be made quickly and safely.

The adjustment is effectedbyascrew device. The screw 30 is mounted in a lateral projection 31 of a ring 32 around the column 2, the said ring being connected with the casing 11, and the screw 30 can be screwed up and down in the base-plate 3, when the casing 11, the cam 27, the supports 9, the nave 8 and the table 40 follow. The screw 30 is rotated by a mitre wheel gearing 34 and a hand-wheel 35. For the shaft 24 there is a groove 36 in the casing, which facilitates the raising of the casing independent of the shaft. When a support with its bottle has passed over the cam 27 and the bottle has got to the vicinity of the conveyor belt 12 it slides over onto the same along the arched railing 37 and is then moved further on the conveyor belt for labelling, packin or the like.

In order t at the bottles may be forwarded to the machine and removed from it in a continuous manner independent of the height position of the supports 9 et cetera, the lateral guides 13 for the conveyor belt have been provided with joints 38, for example two on each side, so that the conveyor within the joints takes part. in the raising and lowering of the table while the remaining part of the conveyor remains in the same vertical position, supported as it is by the uprights 14. Figure 3 shows the belt by dot and dashlines in its lowered position.

The invention, such as it is stated in the following claims is, evidently, not limited to the shown embodiment.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a machine for applying caps to bottles, the combination with capping heads rotating about a central column, of a machine table having supports carrying the bottles and elevating them into said heads, a nave rotating with the latter about the column and carrying the supports for the bottles in upright positions, a frame supporting the nave and machine table, a conveyor for the bottles traversing a portion of the table, and an adjustment device for changing the elevation of the frame and with it the table, conveyor, nave and supports therefor.

2. In a machine for applying caps to bottles,thecombinationwith cappingheadsrotating about a central column, of a machine table having upright supports carrying the bottles and elevating them into said heads, a nave rota'tin with the latter about the column and carrying the supports for the bottles, a conveyor for the bottles traversing a portion of the table, a frame supporting the nave and ANDERS JOSEF JONSSON.
